Which of the following statements about porous disks in voltaic cells is TRUE?
In the Standard Hydrogen Electrode, a platinum wire is used as the electrode. Consider the following standard reduction potentials,
half reactionEo, VZn2+(aq) + 2e---> Zn(s)-0.762H3O+(aq) + 2e---> 2H2O(l) + H2(g)0.00Pt2+(aq) + 2e---> Pt(s)1.20Which of the following statements best describes what would happen if the platinum wire in the Standard Hydrogen Electrode were replaced with a zinc wire? Note: assume that this is the only change made to the half-cell.
In recitation, you examined a diagram of a voltaic cell constructed from zinc and copper in which a tube containing a porous disk and a solution of KCl was placed in each half-cell (recall, the two tubes were not connected). Which of the following statements best describes why this cell has a cell potential of 0.00 V?
Which of the following statements best describes what will happen when magnesium metal is added to an aqueous solution containing 1.0 M ferric ion (Fe3+) at 25oC?half reactionEo, VMg2+(aq) + 2e---> Mg(s)-2.375Fe3+(aq) + 3e---> Fe(s)-0.036a.Mg(s) will be oxidized; Fe3+(aq) will be reduced; the standard cell potential will be 2.339 V. b.Mg(s) will be oxidized; Fe3+(aq) will be reduced; the standard cell potential will be -2.339 V.
